SPECIFICATION forming part of Letters Patent No. 465,212, datedDecemberl 5, 1891. I

Application filed January 27, 1891- Serial No. 379,242. (No model.)

To all whom it may concern:

Be it known that I, GEORGE W. SoHILmNe, a citizen of the United States,residing in the city and county of Philadelphia, State of Pennsylvania,have invented a new and usef ul Improvement in Feedater Regulators,which improvement is fully set forth in the following specification andaccompanying drawings.

My invention relates to improvements in automatic devices forcontrolling the supply of feed-water in boilers, 850.; and it consistsof novel means, substantially as described, whereby steam from theboiler operates a valve in the supply or feed pipe thereof.

It further consists of the combination of parts hereinafter described.

Figure 1 represents a vertical section of mechanism for controlling thesupply of feedwater to a boiler embodying my invention. Fig. 2represents a partly sectional and partly side view of the parts shown inFig. 1 with a portion of a boiler attached, said boiler being shown on areduced scale.

Similar letters of reference indicate corresponding parts in the severalfigures.

Referring to the drawings, A designates a boiler, and B a vessel or tankforming a water-gage, the latter being in communication with the boilerby means of the pipes C and D. lVithin the gage B is a float E, havingits arm F connected with a shaft G, suitably journaled in the sides ofthe boiler. In the supply=pipe H, which leads from any suitable sourceof supply to the said boiler, is secured a valve J the stem K of whichcarries a head L, which fits and worksin a portion of the casing Madjacent to the valve-chamber. A pipe N leads from the upper portion ofthe gage B to a small chamber P in the upper part of the casing M, saidchamber having an outlet-opening Q, controlled by a metallicbalance-valve B, said valve being within the chamber P and controllingthe opening Q in said chamber.

S designates an electric circuit of usual character,-and T anelectro-magnet in said circuit, having a recessed core, in which thestem of the valve R is guided. On the end of the shaft G, which passesthrough a stuffing-box of usual construction on the boiler, is rigidlysecured an arm G, having attached thereto a rod U, the lower end ofwhich is provided with a contact-piece U, adapted to contact with theelectrodes V V of the electric circuit when the water in the boiler isatlow water mark and the float is lowered, so as to close said electriccircuit, and thereby operate the valve B, so as to open said pipeN andopening Q to permit the entrance of the steam into the chamber P and itsescape therefrom, so asso bear against the head L, and thus open thevalve J, turning on the supply of water, or else closing said pipe N andopening Q, any steam entering the chamberpassing above the disk of thevalve R assisting the weight of the valve in closing it, whereupon thespring V of the valve J closes the latter, and thus prevents any furtherflow of water into the boiler.

It will be seen that the parts as described insure the automaticoperation of the valve J, so that the supply of water is reliablycontrolled.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. A boiler having a water-gage with float, a supply-pipe with avalvetherein, a pipeleading from the steam portion of the gage to thevalve-chamber of the supply-pipe, an electric circuit containing anelectro-m'agnet, and a contact-piece, substantially as described, connected with said float for opening or closing the said steam-pipe, saidparts being combined substantially as described.

2. The combination of a water-gage having a float, a water-pipe with avalve-chamber having a pipe connection with the upper portion of saidgage, and a valve in said chamber, provided with a stem having a headthereon, and an electric circuit having an electro-magnet, and acontact-piece connected with and moved by said float and adapted toclose said circuit, substantially as described.

3. A water-gage with float therein, a watersupply pipe with avalve-chamber having a self-closing valve therein, said Valve having astem with a head or disk thereon, a pipe leading from the upper part ofsaid gageinto said valve-chamber above said head, and an electriccircuit normally open, and a contactpiece connected with and operated bysaid float for opening and closing said last-men- 15 scribed.

5. The combination of a Water-gage having a float therein, awater-supply pipe with a casing having a valve-chamber therein, and aseparate chamber above said valve-chamher, a valve with stem and head insaid valvechamber, and an opening in the bottom of said upper chamberabove said head, a valve.

in said upper chamber for opening and closing said opening, an electriccircuit with electro-magnet for operating said latter valve, and means,substantially as described, connected with the float for opening andclosing the circuit, substantially as described.
